This crystalline substance has already been recognized as cardenoride called cerberin. It was crystallized from aqua alcohol, mp. 190~92°C (needle), and showed positive Legal, Baljet and Keller-Kiliani reactions giving a molecular formula of C_<30> H_<46> O_8. A genin of cerberin was estimated as the digitoxigenin by infrared spectroscopy, nuclea magnetic resonance spectroscopy and mass spectroscopic methods, respectively.","subitem_description_type":"Other"},{"subitem_description":"オキナワキョウチクトウ(Cerbera odollam, Gaertner)の生鮮薬に含まれる強心配糖体については、著者の一人が報告した。果実の子葉(仁)には、Cerberinという強心配糖体の一種が含まれ、その糖部分が　Cerberoseであるとして、その構造が松原によってすでに報告されている。しかし、非糖部分(Genin)については、いまだに報告がなされていない。著者らは、子葉からCerberinを単離し、それについて、赤外吸収スペクトル、核磁気共鳴吸収スペクトル、質量スペクトルを、それぞれ測定し、非糖部分がdigitoxigeninであることを推定した。子葉570gをエーテルで油脂類を除いてから、メタノールで抽出する。メタノールを留去して得た茶褐色粘稠物を、さらにクロロホルムで抽出した。クロロホルムを追い出した残留物は、淡黄色粘稠である。これを含水メタノールで再結晶を繰返して無色針状結晶を得た。融点190～192℃、収率:0.09%。Aglyconによる呈色は、Legal反応、Baljet反応、Liebermann反応はともに陽性。糖によるKeller-Kiliani呈色反kも陽性。これらの結果、Scilla-bufo型でなく、digitalis-Strophantus型であることを示し、ジギタリス配糖体に属する物質だと予想した。元素分析値は理論値とよく一致し、質量スペクトルの結果から、分子式はC_<30>H_<46>O_8となる。","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学理工学部"},{"subitem_1522300295150":"en","subitem_1522300316516":"Science and Engineering Division, University of the Ryukyus"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/23509"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN0025080X"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学理工学部紀要. 理学編"},{"subitem_1522650068558":"en","subitem_1522650091861":"Bulletin of Science & Engineering Division, University of Ryukyus.
